EJECTIN'G AND COOKING MECHANISM FOR BREAKDOWN GUNS.

SPECIFICATION forming part of Letters Patent No. 543,366, dated July 23,1895.

Application filed October 12, 1894. Serial No.525fl43. (No model.

To all whom it may concern:

Be it known that we, CHARLES A. YOUNG and SILAs H. BARTON, citizens ofthe United States, residing at Enon, in the county of Clark and State ofOhio, have invented certain new the shell in case the cartridge has beenfired.

A further object of our invention is to simplify the construction ofvarious parts of the gun, so as to cheapen the construction and at thesame time increase the effectiveness thereof.

We attain these objects by the constructions shown in the accompanyingdrawings, in which Figure 1 is a vertical longitudinal section withparts in elevation. Fig. 2 is a similar view taken on a different planeand with some of the parts in difierent positions. Fig. 3 is ahorizontal section of the fore-end, showing the ejector-plungers andtheir controlling devices. Fig. d-is a rear elevation of the main barrelor breech. Fig. 5 is a horizontal section of the breech-block, showingthe firing mechanism. Fig. 6 is a perspective view of one of theejecting devices. Fig. 7 is a similarview shown from a different pointof observation.

Like parts are represented by similar letters of reference throughoutthe several views.

In the accompanying drawings, a represents the stock and b b thebarrels. The stock a is provided in the usual manner with a breechblock(1., having the forwardly-projecting extension a to which the barrels bare hinged in the usual manner-that is to say, by means of a projectinglug 6, formed on the bottom of the barrels and adapted to project into aslotted opening a formed in the extension a The hinge proper of thebarrels is formed at a, at or near the front end of the extension 0. thelug b on the barrels being constructed to conform to the bearing at, onwhich it is adapted to turn, the fore-end 19 being fitted to the saidextension and connected to the barrel to complete the hinge in the usualmanner.

c c are the hammers, each of which is formed integral with a firing-pinc, said hammers being each preferably constructed on the end of a rod orstem 0 which is shouldered down at its forward end to form a reducedportion 0 which extends entirely through the extension at of thebreech-block. The stem 0 has fitted thereon a sleeve 0 and a collar 0The sleeve 0 is slotted at its forward end at c to form a guide for thehammer proper, and between the end of the sleeve 0 and the collar 0 is aspring 0 which serves as the mainspring of the firing-piece. The sleeve0 fits loosely on the stem 0 The collar c is secured rigidly thereto,and when thus mounted the stern, together "with the sleeve, collar, andspring, are inserted into the breech-block, which is bored out to form achamber 0 to receive the same. The sleeve 0 is further provided with adownwardly-projecting lug c and is secured in position in the chamber 0by a retaining-screw 0 so that as the hammer is moved backwardly thestem will slide through the sleeve 0 and the spring 0''" be pressedbetween the end of said stem and the collar 0 The extension .0 on thestem, as before stated, extends entirely through the extension a of thebreech-block, said extension being drilled out for this purpose. It willbe understood that'two of these hammers are employed, and that they arearranged in the breech-block and the extension a thereof on each side ofthe slotted opening 0. into which the lug b of the barrels is extended.

To provide for setting or cooking the hammers as the gun is opened weconstruct'each of said hammers with a laterally-extending lug o whichlugs project inwardly and in line with the vertical arm 0 of abell-crank lever pivoted at 0 The other arm of this bell-crank lever isformed in the nature of a sleeve 0, which is bored out to receive asliding extension 0 which is normally pressed outward by a spring 0arranged within said sleeve, a stop-pin c", operating in a slottedopening 0 in the side of said arm, forming a guide and stop for saidsliding extended portion, which is adapted with the main part of saidbell-crank lever to form a telescoping arm. The outer end of the arm 0is adapted to contact with the lug b of the barrels b, and as thebarrels are turned on their hinge the said lug elevates the arm 0, thuscarrying the arm backwardly into contact with the laterally-extendinglugs o and thus forcing the hammers back so as to cook the same. Each ofthe hammers, or the stem thereof, is provided with a notch 0 into whichthe hook-shaped end of a sear 0 is adapted to engage, said sear beingpreferably formed integral with the trigger 0 The barrels b are providedat the breech with ejector-slides b having forwardly-extending stems bin the usual manner, the ejector-slides for the different barrels beingindependent and having independent stems b Arranged below the barrelsand in that portion of the gun known as the fore-end are placed twoplungers d d. (See Figs. 1 and 3.) These plungers d d fit in suitablebearings in the fore-end, which are drilled out to form chambers d toreceive the same, and each of the plungers is provided with aforwardlyextending stem 61 which projects through said chamber 61 andinto a suitable hearing which is extended beyond said cham ber d. Aroundthis stem 01 and between the end of the chamber d and the plunger 01 isa spring d which, under certain conditions, forces said plunger rapidlybackward, as will hereinafter more fully appear. Each of the plungers dis further provided with an upwardly-projecting spur dfiwhich stands, inits normal position, immediately in line with and at the end of one ofthe stems b of one of the ejector-slidestha t is to say, one of theplungers, through the medium of its spur d engages with one of theejector-slides.

Now it will be seen from the above description, with the parts asdescribed, each time the gun is opened by turning the barrels on theirhinged portion the springs 01 will force the plungers d outwardly,carrying with them the ejector-slides b the plungers being forced backto their normal positions, so as to compress the springs in the usualmanner by the ejector slides contacting with the breechblock when thegun is closed. To provide, however, for operating the ejector-springsand their plungers only at such times as the barrel to which it belongshas been fired, so as to expel only the empty shell, we provide for eachof the ejector-plungers a trip-lever (1 These trip-levers d are pivotedat the sides of the metal portion of the fore-end,in which the ejectorsprings and plungers are inclosed, and each of said trip-levers isprovided with a laterally-extended lug (1 adapted to engage in a notch01 formed in the projection (i on said-plungers. The notches 01 in whichthe lugs d are adapted to engage, are made larger than said lugs topermit the plungers a limited end movement before engaging said lugs,

for the purpose hereinafter more fully exmer-stem extensions beingadapted to project under the trip-levers 01 Now, assuming that oneorboth cartridges'have been fired the hammer-stein extensions areprojected forward into the slotted openings 19 under the trip-levers dThe gun being now opened by turning the barrels on their hingedconnection, the ham mer will be, through the agency of the bellcrankcocking-lever, moved backward. At the same time the trip-levers d will,by the movement of the gun, be carried downwardly, so as to contact withthe ends of said ham merstem extensions, so that just before the hammerreaches its cocked position the trip-levers d will be moved upwardly bythe projecting end of the hammer extensions, so as to release theejector-plungers, which will operate the ejector-slides and forciblyeject the shell that has been fired. If either barrel has not been firedthe hammer remains in a cooked position, in which case the hammer-sternextension stands flush with the forward end of the breech-blockextension and does not contact with its trip-lever d Hence the plungercannot operate to eject the shell. After the shell has been ejected theparts are returned to their normal positions in the manner beforedescribed, the trip-levers (1 being preferably provided with springs 01to cause them to reengage in the plungers when returned to their normalpositions.

To provide for positively starting the shell independent of the actionof the ejectorsprings, we construct the extension a with a hook-shapedlug a which projects upwardly, so as to fit between the plungers d andengage in a recess (1 in each of said plungers. This hook-shapedextension a is so formed that as the barrels are turned so as to openthe same the plungers are moved positively by the action of saidprojection,so as to start the shell in both barrels and move them alimited distance until said plungers contact with the trip-levers, thislimited movement being permitted by the notches or recesses in theplunger projections, as before described. It will be understood that bythis construction the shells in both barrels are started positivelyevery time the gun is opened, so that the ends of said shells arecarried slightly beyond the breech of the gun in a position to bewithdrawn, if desired. If either one or both of said shells have beenfired, but not otherwise, it will be further acted upon by theejectorspring and discharged from the gun.

It will be seen from the above description that an extremely simple andeffective firing mechanism is provided, the construction being also ofsuch a nature that when fired the shells will be positively ejected fromthe barrels.

By having the cocking'lever in two parts, adapted to telescope, asdescribed, we are enabled to put the parts of the gun together in eitherposition of the hammers, whether cocked or not, the sliding portion ofsaid cooking-lever being adapted to move back out of the way to permitthe entrance of the lug.

It isobvious that the ejector mechanism herein described could be usedwith any other form of firing mechanism, providing a suitable extensionis formed on the hammers or other moving parts to operate the trippingmechanism of the ejeotor-plungers, in order that the ejector-plungersshould be operated only after the hammers or firing mechanism has beenoperated.

Having thus described our invention, we claim- 1. In a gun, a hingedbarrel, a hammer, a sear for holding said hammer, and a spring foroperating the same, a pivoted cocking lever independent of said hammerbut adapted to engage therewith, said cockin g lever being formed in twoparts, one adapted to telescope in the other as described, thetelescoping part being projected so as to engage with said hingedbarrel, substantially as specified.

2. The combination with the hinged barrels having an extended lugthereon, spring-actuated hammers for said barrels, and means for holdingsaid hammers when the springs are compressed, laterally-extendingprojections on each of said hammers, and a pivoted lever between saidhammers adapted to engage said projections, said lever being providedwith a spring-pressed telescoping arm to engage said lug, substantiallyas specified.

3. The combination with a hammer formed integral with a firing pin andextended stem as described, a sleeve on said stem provided with aslotted opening to receive and guide said hammer, a collar secured tosaid stem, and a spring between said sleeve and collar, and means,substantially as described, for holding said sleeve as the spring iscompressed, substantially as specified.

4. In a gun, a hammer formed integral with a firing pin and extendedstem as described, a sleeve on said stem adapted to guide said hammer,and a collar secured to said stem, a spring surrounding said stem andbetween said sleeve and collar, a laterally extending projection on saidhammer, and a pivoted lever adapted to engage said projection, saidlever being extended so as to engage the hinged barrel of said gun,substantially as. specified.

5. In a gun, a hinged barrel having a projecting lug, a pivoted leverformed in two parts adapted to telescope as described, a hammer formedintegral with a firing pin, and a projecting stem having a springthereon,

' a scar for engaging said hammer, said pivoted lever being adapted toengage with said hammer when moved by said hinged barrel, substantiallyas specified.

In testimony whereof We have hereunto set our hands this 8th day ofOctober, A. D. 1894..
